Length: w + 2

width: w

A = L x w

143 = (w + 2)(w)

143 = w² + 2w

0 = w² + 2w - 143

0 = (w + 13)(w - 11)

0 = w + 13                           0 = w - 11

Negative so disregard            w = 11

Length: w + 2  = 11 + 2  = 13

Perimeter = 2L + 2w

                = 2(13) + 2(11)

               = 26 + 22

              = 48

Answer: 48 ft
